In a large resealable plastic bag, combine the first five ingredients; add the chicken & kielbasa. Seal bag & turn to coat. Refrigerate for a minimum of one hour. Meanwhile, place potatoes in a large microwave-save bowl. Cover & cook on high for 6-8 minutes or until almost tender, stirring twice. Drain & discard marinade. Using soaked wooden skewers, alternate the chicken, potatoes, kielbasa & pineapple. Continue until all meats, potatoes & pineapple have been placed on the skewers. Grill over medium heat for 10-15 minutes, turning frequently.
